src/main/resources 文件被 src/test/resources 覆盖

Question

我使用 spring-boot 实现了一个 Web 服务。它在初始化期间从文件中读取。所以我将文件创建为src/main/resources/files/init_file.txt。这是一个巨大的文件，在初始化期间需要一些时间来阅读。无论如何，Web 服务能够从文件中读取并按预期工作。

然后我添加了单元测试。由于这个文件很大，我使用了一个轻量级的虚拟文件，我创建为src/test/resources/files/init_file.txt。请注意，此虚拟文件位于 src/test/resources 中，而不是 src/ma​​in/resources 中。

单元测试按预期工作。但是，现在当我运行服务 (mvn exec:java) 时，服务总是从测试资源中读取虚拟文件。

如何确保 Web 服务读取正确的文件？

我也尝试使用<excludes> 排除src/test/resources/*，但没有成功。

Answer 1

Exec 让你指定classpath scope。

可以设置为compile,test,runtime或system（默认为runtime）。

OP 设置为测试：

<classpathScope>test</classpathScope> 

要么删除它，要么从命令行指定类路径范围：

mvn exec:java -Dexec.classpathScope="runtime"
